Within the mitochondrion’s inner membrane

The right answer is C. Within the mitochondria’s inner membrane.

The mitochondrion is limited by two membranes of very different properties:

* the outer membrane contains a transmembrane protein, porin, which allows the passage of ions and water-soluble metabolites of molar mass <10.000 Da.

* The inner membrane is very rich in proteins and almost impermeable to ions and water-soluble metabolites.

The respiratory chain or electron transport chain is located in the inner membrane of mitochondria. Each mitochondrion contains thousands of copies of the electron transport chain.

the correct answer is - d. china has a large and growing population.

the fact that china has a large (the biggest) population, and it is still growing, doesn't hinder the agriculture production in the country. in fact, it can for increased production in the agriculture, since there's more labor force, as well the sheer mass of people produces lots of scientists that come up with new inventions as to how to improve this sector. nice example is the inner mongolia region in china, in general dominated by the gobi desert, but few scientist came up with a nice idea as to how to make the region productive by using plants that are very resistant to droughts, so lots of people have been employed, and the region is becoming greener and greener each year, and the production of food in this region is also increasing.
